Abstract: One or more techniques and/or computing devices are provided for directory level incremental replication. For example, a first storage controller may evaluate a base snapshot and an incremental snapshot of a source subdirectory to generate a set of operations that can be used by a second storage controller for reconstructing a mirror of the source subdirectory as reflected by the incremental snapshot. Accordingly, the first storage controller may send the set of operations and/or source data to the second storage controller for constructing a destination directory structure mirroring the source subdirectory. In this way, replication may be achieved at an arbitrary level of granularity, such as to replicate a particular subdirectory of a volume.

Abstract: One or more techniques and/or computing devices are provided for non- disruptively establishing a synchronous replication relationship between a primary volume and a secondary volume and/or for resynchronizing the primary volume and the secondary volume. For example, a baseline snapshot and one or more incremental snapshots of the primary volume are used to construct and incrementally update the secondary volume with data from the primary volume. A dirty region log is used to track modifications to the primary volume. A splitter object is used to split client write requests to the primary volume and to the secondary volume. A synchronous transfer engine session is initiated to processing incoming client write requests using the dirty region log. A cutover scanner is used to transfer dirty data from the primary volume to the secondary volume. In this way, a synchronous replication relationship is established between the primary volume and the secondary volume.

Abstract translation: 提供了一种或多种技术和/或计算设备，用于不中断地建立主卷和次卷之间的同步复制关系和/或用于重新同步主卷和次卷。 例如，主卷的基准快照和一个或多个增量快照用于构建并增量更新来自主卷的数据的辅助卷。 脏区日志用于跟踪对主卷的修改。 分离器对象用于将客户端写请求分割为主卷和辅助卷。 启动同步传输引擎会话以使用脏区日志处理传入的客户端写入请求。 切换扫描器用于将脏数据从主卷传输到次卷。 这样，主卷和辅助卷之间就建立了同步复制关系。

Abstract: One or more techniques and/or computing devices are provided for replicating virtual machine disk clones. For example, a first storage controller, hosting first storage, may have a synchronous replication relationship with a second storage controller hosting second storage. A virtual machine, within the first storage, may be specified as having synchronous replication protection. Accordingly, virtual machine disk clones of a virtual machine disk of the virtual machine may be replicated from the first storage to the second storage. For example, virtual machine disk clones may be synchronous replicated, replicated by a resync process invoked by a hypervisor agent, and/or stored and replicated from a clone backup directory.
